Y i' Y This inventionyrelates to harvesters and it relates particularly.to hafrvestersr for har- Vvestingvvine crops, such'fas peas,rv .l

In harvesting peas by use-of machinery, l5 isnecessaryfthat a sickleknife beusedj'which rides directly on the ground iny order that the 1*entire'cropbe cut.- If a knife similar tothe knife of an ordinary moweris used,tl1e dirt from the field, particularly if moist, will soonaccumulate on the .-hottomof the cutter bar Vbetween the knife.. guardsand this dirt will graduallyhuildiup to interfere: withV theVprop'e'rfaction `of 4the sickle' bar-fand 'sickle knife. vIt is,4therefore, f ydesirable Y to provide l means for preventingthefaccuinulation of` Y dirtbetween the guards and-the cutterbar; f

' VIn theV northwestern part of thefUnited States, peasy areextensively-raised for can-Y ning purposes.V y'Ihe-can'ning factorieslocate ',30 value of the-peas-forcanning purposesconsiderably. Itis,therefore, desirable to `-pr0- vide, ina pea harvester,'anrelevatorwhich Vcan be used in connection with'a sickle ,knife riding `on theground and ,will gather the crop as..

rearendof the push bar 19 is, of course, pivoted to the housing 8.Pivotally secured to -the member 18 is the inside shoel 20 .ofthe sickleknife rand acutter bar 21 issecured to this shoek and extends towardt-heright end of the'machine. The cutter bar has the usual guards 22mountedv on the lower side thereof and projecting forwardly from thecutter bar in spaced relation and these guards have grooves 22a `in,their upper faces adjacent their rear ends within which the sickle bar23 is disposed. Thepitman 14is of course pivotally connected at itsright endftoy the sickle bar 23 and the sickle bar carries the usuallblades 24, which bear against and work over oooperating'blades 25mounted in the guards 22. Knife holders 26 are mounted on the cutter bar21 at spaced. points tohold. the sickle blades 24 adjacent the guardblades 25. lA divider 27l is secured to the right end of the cutter bar21. As the sickle knifeused isof'standard construction for mowers,.thereis no need of going into further detailed description of the same. Grainsaver guards 28 are mounted on certain of the guards 22and thesegrainsaver guards are also of standard construction and includemerelybrackets 28a clamped by plates`28b and bolts 28ov to the forward ends ofthe guards 22. and secured by certain of the bolts 29 to the cutter bar21,

. which bolts 29, are those which secure the guards 22 to the cutter bar21. The grain saving guards 28 also include pointed and upwardly curved.members 28d pivoted tothe brackets28a and terminating in arms. 22eloofthe cutter bar 2l` and. this plate is curvedr upwardly andrearwardly from the cutter rearwardl to the draw bar 17 of the mac ineand to t e housbracket E15-.and the backboard 33.

tically disposed and inclined frontboa'rd 3T which is shaped to lit thebottom of the cutter bar and to encompass the guards 22 at the rearportions. of their lower surfaces, and to lit upwardly between adjacentguards 22. The forward portion of the plate 30 accordingly extends belowthe sickle bar 23 and curves` upwardly between. the 'guards 22 andtively,are downwardly projecting arms 32 to! which. a. backward 33k foran elevator is' secured.. They backboard 33 isvertioally disposed andruns parallel to thehousing 8 berhindlthe sickle knife and' then extendsinninclined relation to a point outwardly'disposed from' the leftside'o.the machine well above the Aleft Wheel- 1,0.y A vertical end bored 34is secured Vto the right end of the black- 'boardvk 33 and' projectsforwardly therefrom andy this and board carries a small bracket? i 35-which projects toward they left' side of the machine at they lower-edgeof 'the end board; `A roller 36e-is journaled inthe A verisimountedinparallel relation to the inclined portion of the backboard33fas bymeans of rods38 and an-.upper roller 39 is journaled in the upper4 endsof thel backboard33 and the l l front board. 37 adjacent lthe loweredges thereof. An endless belt 40 preferably having slats 41 on itsouter surface-runsvover the lrollers 36 and-39-aud over rollers 42carried by thebaokboard 33 adjaoenttheV lower end of the-inclined4portion thereof and also carried by the front board 37 adjacent thelower end thereof. A shaft 43y carryinga sprocket 44 isjournaled inagear casing 45 secured to the housing' 8 and containing gears 'suitablydriven from the left wheel 10 of themachine.

A longarm 46, is securedto the housing '8 adjacent its left. end andthis arm runs upwardly `and formsa bearing for a counter shaft 47 alsojournaled in a bearing 48 carried by. the

backboard ylvadjacent its upper end. A

The tin'es 62are of such length kthattheywill extendto points adjacent the guards 22 for the sickle knife asthedrumis rotated. Coiled Springs 63 surround the rods 6l adj facentthelefty side Y and' in acounter clockwise'direction as viewed inFig-s. 3and 4. The right ends of the'rods choredatone end lin thehead 56 andareanchored fat the other end in the respective rods. The springs y63accordingly place the.

'rod S61 and the tines 6 2 carriedfthereby under resilient tension ltomove in the same direction as the directionofrotation of the drum 6lprojectV beyond the right side of the head v56 l and.v carryk arms. .64thereon, which project infan oppositedirection from the rods than theAdirection ofextension of'the1tines62 andV stop screwsv 65are-fadjustably. mounted 'in ears-66carried Voni thejright side of thehead 56;' Stop -'screwsx65 are adapted vto engage the arms V64V to limitmovement of therod 61 in a counter'clockwise direction as VviewedfinFigs. 3 and 4 andfoccasionedl by thesprings 63. yThe arms 64-also carryweights 67 which counter balance or partially'counter balance theweightof Ythe tines A62,so that the/rods 6l inaybereadily' swungin the'heads' 56 and A @57; k*Angular arms@ 68 are carried at Ythe aextremeright end ofthe rodslfor .cooperation witha horseshoe-shaped'cain 69mounted'on'the vright arm 58.1- The cam 69 'is disposed with itsopenportion downwardly as best shown-in Fig.w4fand the arms 68 are of suchlength that during.` rotation of the drum, these arms vwill ,strikev thefcamf69f shortly after the lower ends .of 4thetines 62have been carriedto-a position above the upper fhori- Zontal` run of thee'ndle'ssbelt 40ofthe. elevator; As the drum continues to rotate after anA arm 68has'engagedthe'inner surface ofr the cam 69., the rod 6l toV whichthe said'arm 68 is attached', will-be swung in a clockwisey direction as viewedin yFig'f'xand in VFig.4,

to carry the'tines tov amore nearly vertical position over the belt40.'` In other words, y

thejtines62- carried bythe rods 61 acted on bythe cam 69 will beswungfinah direction 68 ,from the forward lower vendL of the Cam 69.4;the spring"63will quickly swingthe-rod -6linvthe same direction'asthedirectionl of rotation of thel drumand until'the-'arm 64 strikes the top,screw cooperating ltherewith.y The tines 62on the r`particular-rod'61.'in'questiom will accordinglybe swung quickly downwardly and rearwardlyto points adjacent the grain saving guards :28.y -f

yThe. operation ofthe machine is 'probably obvious from the abovedescription. Asthe vmachine is `drawn along the field in whichthe peasory other crops to be harvested are groW- ing,.the tines k62 onthevarious rods 6lwill be successivelyy swung downwardly to carry the peasand vines intoy thesickle knife'. Asy

the sickle knife'rides directly .on the ground andhas freedom fortilting action vto conform Vgenerally to ftheshape ;of the ground, the

sickle knife will cut Vthe vines close to 'the ground.4r The tines 62will carry the vines and peas .over the grain saving guards 28 fandsickle knifeandover the upwardlyinclined portion of the plateOto a pointabove the fupperrun of the horiontal portion of the beltk 40 of the.elevator,i.-,At this point thecam-69 will act' to [swing thetine621to'tilt them toal more nearly vertical position and therebycause.l

v`the vines `and peas to slide downwardly onthe 'tines ontotheelevator'ibeltlO.' The elevator will then deliver'the vines and :peas.over ythe f 'left side lof the machine to 'dischargeinto a E lwmon,which may be driven in the field at the left'side ofthe machine. As theyrods 61 `are canriedto. a position adjacent the lower 'fortwardendofthe cam 69 during rotation of thednum, the rods will be quick-ly swungn aly separated fromy the vines and shelled.

' jeeting outwardly therefrom, means forro-y Itwillbe seen that themachine is capable of variousadjustments. The forwardk ends ofthe arms53 and 54may be variously located relative to the cutteriknife andtheextent of movement kotfitherods 61 maybe readily by yadjustmentof thestop screws 65 in the ears/66' e Thedevice is quitesimple inconstruction and in operation. f

It will, of course, bevunderstood that various changesmay be made in theform, details, arrangement and proportionsof the various parts withoutdeparturek from the scope of the ypresent invention, which generallystated -consistswin thevmatter shown. and described and'aet forth in theappended claims.
